Abstract
The present experiment entitled “Studies on effect of post-harvest treatments and storage conditions to enhance shelf life of ber (Ziziphus mauritiana L.)” was conducted in the Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2019-20. Fruits were treated with post-harvest treatments viz. lemongrass oil 0.1%, til oil 2%, Aloe vera 100%, salicylic acid 1mM, calcium chloride 2%, citric acid 0.5%, sodium nitroprusside 1mM and control. Fruits were stored at room temperature as well as cold storage conditions. The minimum loss in weight, decay loss and maximum colour, specific gravity, sugars and total chlorophyll content were recorded in fruits treated with Aloe vera 100%. The maximum fruit firmness was observed in fruits treated with Aloe vera 100% and salicylic acid 1mM whereas, maximum ascorbic acid was observed in calcium chloride 2%, salicylic acid 1mM and Aloe vera 100% treated fruits at room temperature storage.
The minimum loss in weight, decay loss and maximum fruit firmness, specific gravity, organoleptic quality and total chlorophyll content were maintained by fruits treated with Aloe vera 100% under cold storage conditions. The maximum ascorbic acid content, total soluble solids and sugars were observed in fruits treated with calcium chloride 2% under cold storage conditions. The maximum free radical scavenging activity was observed in fruits treated with salicylic acid 1mM under both room and cold storage conditions. Loss in weight and decay loss increased with prolongation of storage period whereas, ascorbic acid content, acidity, fruit firmness and specific gravity decreased with the advancement of storage period under both storage conditions.
